Dundee manager Tony Docherty believes Dundee were punished for failing to maintain their sterling work in the first half against Celtic during the critical period just after half-time. The visitors were forced to pass the ball around between themselves before the second half got underway as Dundee kept their opponents waiting before emerging after the break. But it was the hosts who were caught cold seven minutes later as Luis Palma’s angled ball inside the Dundee defence was poked in by Paulo Bernardo for the opener in the eventual 3-0 defeat, with substitute Mikey Johnston grabbing a late double. “I was pleased at half time," said Docherty. "We limited Celtic to few chances and our defensive structure was good. I was asking the players to improve their ball retention in the second half. The first 10 minutes of the second half are really important when you play against the Old Firm and I warned the players of that. “It was important we kept that defensive structure but there were a couple of wee chances just before the goal. They got their goal, I thought it was fortunate. But once they got the goal, you see the quality Celtic have." Dochery lost striker Diego Pineda in the warm-up and then substitute Zach Robinson just a few minutes after he came on in the second half. “He (Robinson) got a sore one,” said Docherty. “On the way out from the corner he caught one in his hip. And we lost Diego Pineda, who got injured in the warm-up. I was limited with our striking options.”
